I believe that you're right about the animations, as is Randall. Solutions 
need to be multisensory (text, voice, motion, etc.) so that they cover 
differences in learning styles as well as a variety of things from 
disabilities to literacy issues to language issues. Animations aren't bad 
for all people and can actually be helpful for some, such as the people 
with dyslexia you reference. I believe that this is where useability and 
universal design principles need to converge with accessibility efforts.

I might be wrong (and that has happened often) but I was under the 
impression that animation was fine if it could be turned off? In studies 
that I have seen by agencies that work with dyslexics, they actually like 
animations and they are a large proportion of the disabled community 
(numbering 5 million in the UK alone).

I think some clarification is needed.

screen to flicker.


Not all animation causes flickering of the screen.  Images that rotate
quickly might, and should be avoided, but certainly not a smooth 
such as you are capable of with Flash animations (but that's another topic
altogether regarding accessibility).
